CVE-2021-41247 – incomplete logout in JupyterHub
https://notcve.org/view.php?id=CVE-2021-41247
JupyterHub is an open source multi-user server for Jupyter notebooks. In affected versions users who have multiple JupyterLab tabs open in the same browser session, may see incomplete logout from the single-user server, as fresh credentials (for the single-user server only, not the Hub) reinstated after logout, if another active JupyterLab session is open while the logout takes place. Upgrade to JupyterHub 1.5. For distributed deployments, it is jupyterhub in the _user_ environment that needs patching. There are no patches necessary in the Hub environment. • https://github.com/jupyterhub/jupyterhub/commit/5ac9e7f73a6e1020ffddc40321fc53336829fe27 https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-cw7p-q79f-m2v7 • CWE-613: Insufficient Session Expiration •

https://notcve.org/view.php?id=CVE-2019-10255
An Open Redirect vulnerability for all browsers in Jupyter Notebook before 5.7.7 and some browsers (Chrome, Firefox) in JupyterHub before 0.9.5 allows crafted links to the login page, which will redirect to a malicious site after successful login. Servers running on a base_url prefix are not affected. Una vulnerabilidad de redirección abierta para todos los navegadores en Jupyter Notebook, en versiones anteriores a la 5.7.7, y en algunos navegadores (Chrome, Firefox) en JupyterHub, en versiones anteriores a la 0.9.5, permite que los enlaces manipulados accedan a la página de inicio de sesión, lo que redirigirá a un sitio malicioso después de un inicio de sesión exitoso. No se ven afectados los servidores que ejecutan un prefijo "base_url". • https://blog.jupyter.org/open-redirect-vulnerability-in-jupyter-jupyterhub-adf43583f1e4 https://github.com/jupyter/notebook/commit/08c4c898182edbe97aadef1815cce50448f975cb https://github.com/jupyter/notebook/commit/70fe9f0ddb3023162ece21fbb77d5564306b913b https://github.com/jupyter/notebook/commit/d65328d4841892b412aef9015165db1eb029a8ed https://github.com/jupyter/notebook/compare/05aa4b2...16cf97c https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UP5RLEES2JBBNSNLBR65XM6PCD4EMF7D https://lists.fedoraproject.org/archive • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
